Subject: [PATCH v2 2/2] ARM: dts: sun8i: Enable i2c controllers on ippo-q8h-v5

i2c0 is connected to the gsl1680 capacitive touch panel controller.
i2c1 is connected to an mma7660 3-axis accelerometer.
i2c2 is connected to the front and back gc0309 camera sensors.
The camera sensors require additional regulators be enabled before
they are available.

All these peripherals are not supported by the kernel yet.
